RationalDMIS 7.1 平面 圆 圆 构建坐标系

（1）分别测量基准圆MA_CIR_A和MA_CIR_B（2）建立公共轴线MA_AXI_X（3）找正坐标系X+(这步非常重要)（4）测量上平面MA_PLA，确定第二轴向Z+。（5）测量左平面MA_PLA_A（6）确定坐标系原点（平移）$$/* HeaderDMISMN/'Created by [爱科腾瑞科技(北京)有限公司-091520-DEM] on Friday, April 17, 2020', 4.0UNITS/MM, ANGDEC, MMPSWKPLAN/XYPLANPRCOMP/ONTECOMP/ONFLY/1.0000MODE/MANSNSET/APPRCH, 2.0000SNSET/RETRCT, 2.0000SNSET/DEPTH, 2.0000SNSET/SEARCH, 10.0000SNSET/CLRSRF, 15.0000RECALL/D(MCS)SNSLCT/S(L20-D2.0)GEOALG/BF, LSTSQRGEOALG/ANGLB, DEFALTGEOALG/CIRCLE, LSTSQRGEOALG/ARC, LSTSQRGEOALG/PLANE, LSTSQR$$$$$$*/MODE/MANSNSLCT/S(L20-D2.0_A90_B90)F(MA_CIR_A)=FEAT/CIRCLE,INNER,CART,5.2856,0.0000,0.0000,-1.0000,-0.0000,-0.0000, 50.0000$$ Measurement points are created through actual pointsMEAS/CIRCLE, F(MA_CIR_A), 4 PTMEAS/CART, 5.2856, -1.2147, -24.9705, -0.0000, 0.0486, 0.9988 PTMEAS/CART, 5.2856, 24.2045, -6.2564, -0.0000, -0.9682, 0.2503 PTMEAS/CART, 5.2856, 3.9194, 24.6909, -0.0000, -0.1568, -0.9876 PTMEAS/CART, 5.2856, -24.2862, -5.9312, -0.0000, 0.9714, 0.2372ENDMESSNSLCT/S(L20-D2.0_A90_NB90)F(MA_CIR_B)=FEAT/CIRCLE,INNER,CART,142.6636,0.0000,0.0000,1.0000,0.0000,0.0000, 40.0000$$ Measurement points are created through actual pointsMEAS/CIRCLE, F(MA_CIR_B), 4 PTMEAS/CART, 142.6636, 19.1749, -5.6853, -0.0000, -0.9587, 0.2843 PTMEAS/CART, 142.6636, -5.5074, 19.2268, -0.0000, 0.2754, -0.9613 PTMEAS/CART, 142.6636, -17.8849, -8.9516, -0.0000, 0.8942, 0.4476 PTMEAS/CART, 142.6636, 6.5121, -18.9101, -0.0000, -0.3256, 0.9455ENDMES$$ CREATED BY : External-Array Software, Inc$$ DATE : Jan 19, 2009$$ DISLAIMER: $$ This Macro has been tested internally but not been tested with$$ other DMIS compatible software.
